1,000 true fans is step #1, whether you want a $100K per year business or the next Uber. I’ve seen this with all of my fastest-growing and most successful startups. They start laser-focused on 100 to 1,000 people, niche-ing down as necessary with their messaging and targeting (demographically, geographically, etc.) to get to a manageable and cost-effectively reachable number.
